A student finds a tool that measures adaptability that she wants to use for her master's thesis. It has 25 items, and they are all of the ordinal level, scaled 0 through 5
The level of measurement of the tool is said by its authors, pragmatics all, to be which of the following?
a. Ratio level
b. Interval level
c. Ordinal level
d. Nominal level
ANS: D
Pragmatists often treat ordinal data from multiple item scales as interval data, using statistical methods to analyze them such as the Pearson's Product-Moment Correlation Coefficient, t-test, and analysis of variance (ANOVA), which are traditionally reserved for interval or ratio level data. Fundamentalists insist that the analysis of ordinal data be limited to statistical procedures designed for ordinal data, such as nonparametric procedures.
